What about the name.
The big question is “Where did the name Ferrous Engineering come from?”
In the blacksmithing community each smith names his/her shop (the shop is the smithy). I have a background in chemistry and wanted to include iron in the name of my shop. Iron’s chemical element symbol is Fe which comes from the Latin word for iron, Ferrum. Iron has several oxidation states and in chemistry and ferrous is used in the name of chemical compounds for one of those oxidation states. I happened to like the sound of ferrous. Using the letters F and E from the chemical symbol for iron (Fe), ferrous obviously works for the letter F. For the letter E came engineering and thus the name Ferrous Engineering. And the initials of the business name are F and E which also matches the chemical symbol for iron (Fe). So it was a quite a simple process to name the shop and now the business Ferrous Engineering, at least to a chemist.
